Long shots require the greatest precision and the highest magnification. This special reticle has
been designed to be used at your scope’s highest magnification; the ballistic function of this
reticle will only work at your scope’s highest magnification.
Using the Reticle with a 100 yard Zero

As this reticle will enable you to take shots at extreme distances, it is essential that the target
is qualified through the use of high powered binoculars or a spotting scope and that the distance
has been precisely determined with a laser range finder or other accurate means.
At extreme distances, many factors can affect the trajectory of your bullet. It is recommended
that test firing at these distances be done before attempting shots on game.
